SHOE-SPRING.

SPECIFICATION forming part of Letters Patent No. 585,582, dated June 29,1897. y

Application filed July 20, 1896.

To @ZZ whom it may concern:

Be it known, that I, EMANUEL A. LONGS- DORF, a citizen of the UnitedStates of America, residing at Wichita, in the county of Sedgwick andState of Kansas, have invented certain new and useful Improvements inShoe- Springs, of which the following is aspeciiication, reference beinghad therein to the accompanying drawings, and the figures of referencethereon, forming a partof this speci- Iication, in which- Figure l is abottom plan of an insole of a shoe with my improved shank and solespring attached. Fig. 2 is an edge view of the same.

-Fig. 3 is a side view of the sole and shank springs disconnected, andFig. 4. is a detail view of said springs.

This invention relates to certain improvements in shoe-springs; and itconsists of a shank-spring and a supplementary or sole spring having ashield for the free end of said shank-spring, and the object is toprevent the free end of said shank-spring from Wearing and forcingitself through the sole of the shoe.

Referring to the drawings, l represents an ordinary shank-spring securedto the insole 3, as shown at 5.

2 represents a sole or supplementary spring secured at the toe and ballof said insole 3, as shown at 5. 4 represents an opening in the SerialNo. 599,899. (No model.)

free end of said supplementary spring 2 and is for the purpose ofallowing the free end of said shank-spring 1 to enter, passing under theportion and over the portion 7 of said supplementary spring, where itcan Work freely laterally as the sole of the shoe bends, as while Walking. 1t will readily be seen that by the use of this supplementary springit will be impossible for the free end of the said shank spring to wearand force its Way through the sole.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is as follows:

\ 1. The combination of a shank-spring secured at one end to an insoleof a shoe, and a supplementary, or sole spring, secured at one end tosaid insole, said sole-spring having an opening in its free end, throughwhich the free end of said shank-spring passes.

2. The combination of a shank-spring for a shoesecured to an insole ofsaid shoe at one end, and -a supplementary vor sole springV adapted tohold the free end of said shankspring, from wearing through the sole ofsaid
